Title: Nozzle body of vacuum cleaner
Inventor: OMOTO SHUHEI
IPC: A47L9/02
Filed: 1991-07-24
Abstract: PURPOSE:To provide a nozzle body of a vacuum cleaner capable of being readily reversed even when the nozzle body is reversed and of surely stopping its driving means even under overloads. CONSTITUTION:When an electric motor 9 is actuated as the advance of a vacuum cleaner is detected by a changeover switch 28, the electric motor 9 is rotated in the direction of the advance. If load current flowing through the electric motor 9 rises, an operation amplifier OP1 outputs L level and the output of an OR circuit OA 2 is bypassed and a driving circuit 41 stops the electric motor 9. When the retreat of the cleaner is detected by the changeover switch 28 the electric motor 9 is rotated in the direction of the retreat;then if the load current flowing through the electric motor 9 rises, the operation amplifier OP 1 outputs L level. Then a transistor TR 3 is turned on and the output to an inverter circuit Inv 2 is bypassed to make the condition similar to that when the changeover switch 28 is switched to the mode of the advance, thereby reversing the electric motor 9.

Title: Film winding device for camera
Inventor: YAGI MICHIO
IPC: G03B17/00
Filed: 1980-12-29
Abstract: PURPOSE:To wind a film easily without requiring the operation for mode switching, by rotating a driving source in directions opposite to each other for winding and rewinding respectively and by switching automatically the connection of an advancing shaft and a rewinding shaft to the driving source by this rotation in directions opposite to each other.

Title: Semiconductor device
Inventor: WADA YASUO
IPC: H01L27/088
Filed: 1985-08-26
Abstract: PURPOSE:To control threshold voltage precisely by containing a voltage comparison circuit consisting of an insulated gate type field-effect transistor in which a drain and a source are arranged in the same direction to a gate. CONSTITUTION:When MOSFETs having the same two structure are juxtaposed, the first MOSFET1 uses an upper diffusion layer 2 as a source, and the second MOSFET3 employs a lower diffusion layer 4 as a source. Each transistor has gates 5 and contacts 6, and is connected electrically to the outside by aluminum wirings 7. The threshold voltage of the two MOSFETs in such arrangement does not take the same value. The VTH of an element in which the source is positioned in the same direction to a gate is kept constant in a wafer, and the difference of VTH depends upon only the arrangement of the MOSFETs. The disposition of the MOSFETs is aligned in the same direction in a circuit comparing voltage, thus obtaining excellent circuit characteristics.

IPC: H01L21/60
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a flexible circuit board, where bumps for connection with a circuit part such as an IC chip can be formed without plated lead or the like.

Title: Pll modulator for radio calling transmitter
Inventor: SAEKI SHUICHI
IPC: H04B7/26
Filed: 1991-07-01
Abstract: PURPOSE:To prevent a transmission center frequency from being deviated regardless of a coding rate of a modulation signal by providing a sample-and-hold circuit to a PL loop. CONSTITUTION:A synchronizing signal detection circuit (g) monitors a modulation signal, detects a synchronizing signal sent periodically in a prescribed signal pattern and sends a detection pulse to a PLL control circuit (h). The PLL control circuit (h) measures a prescribed time based on a pulse from the synchronizing signal detection circuit (g) and sends a control signal to a sample- and-hold circuit (i) by a time width of the synchronizing signal in a timing when a succeeding synchronizing signal comes. The sample-and-hold circuit (i) outputs a phase signal from a low pass filter (d) to an adder (a) as it is when the control signal comes from the PLL control circuit (h). When the control signal from the PLL control circuit (h) is stopped, a just preceding phase difference signal is latched and fed to the adder (a). Thus, even when a ratio of 1, 0 in the modulation signal is not impartial, the center frequency of the transmission signal is not deviated.

Title: Shackle
Inventor: FUJIYAMA TETSUO
IPC: F16B45/04
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To improve durability of a rope and a shackle pin to be used by fitting/installing a rope hooking roller having a prescribed outside diameter to/on the outside of the pin installed between both end parts of a substantially inverse U-shaped shackle main body. SOLUTION: A roller 3 is fitted and installed around a pin 2 installed between both end parts 11 and 12 of a substantially inverse U-shaped shackle main body 1. A peripheral groove 33 is formed on an outer periphery of the roller 3. This shackle Y is used by hookingly fastening a shackle upper part 13 by a hook 4 of a crane or the like after a rope 5 to suspend and hold a heavy article W is wound round and hooked on an outer periphery of the roller 3. At this time, the rope 5 is fitted in the peripheral groove 33 of the roller 3, and prevents positional dislocation. Since curvature of a roller winding-hooking part 5b of the rope 5 becomes large in a suspending-holding condition of the heavy article W, a damging degree by bending of the rope 5 is sharply reduced.  Since an inside surface of a central hole 31 of the roller 3 contacts almost over the total length with the pin 2, burden weight can be dispersed, and durability of the pin 2 itself is also improved.

Title: Priority control method when congestion occurs
Inventor: CHICHII TAKEYA
IPC: H04L12/28
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To assure communication quality in a class with high priority rather than communication quality in a class with low priority when a buffer is depleted by transferring refusal of data reception to a priority class buffer at the input side which is specified by a structuring definition when consumption of the buffer exceeds a specified amount. SOLUTION: In a priority class buffer 323 in a group of priority class buffers 32 at the output side, the refusal of data reception is informed to the priority class buffer 314 in a group of priority class buffers at the input side which are previously specified when a pointer 633 to indicate a use state of the present buffer exceeds a specified value by pointers 631, 632 to control allocation amount of the buffer and the pointer 633. Data transfer to a priority class buffer 324 is stopped from the priority class buffer 314. Thus, the buffer is preferentially allocated to the priority class buffer 323 by securing the remaining buffer of the priority class buffer 324.
